DataTypes

BOOLEAN – True/False[0 or 1]

The boolean data type has two possible values, either true or false. The default value is false. The implementation of Boolean is as follow

class Main {
  public static void main(String[] args) {
    	
    boolean flag = true;
    System.out.println(flag);    // prints true
  }
}

BYTE

The byte data type can have values from -128 to 127 (8-bit signed two’s complement integer). The usage of this datatype strictly depends on the range that is going to be in-between the rage that the datatype supports. The implementation will be as follow

class Main {
  public static void main(String[] args) {

    byte range;
    range = 124;
    System.out.println(range);    // prints 124
  }
}
